Begin by writing the KVL equation for the mesh labeled i1i1 by setting the sum of all of the voltages around the mesh to zero. Construct the KVL equation for this mesh by setting the sum of the voltage drops around the mesh (in the direction of the mesh's current) equal to zero. Make sure each term in the equation is expressed in volts.
